Hi everybody,

I have a problem with my MS-2. It turns on but produces no sound. I took it apart but visually all components and connections seem fine. I haven't tested them, and I'm not sure what I should test. I see that there is a link to a guide, on this page, but the link doesn't work. Did anyone experience the same problem ?

Thank you for your help !

Links are explicitely leading to an error404 page. I mean the page isn't missing, the link is built to show up this 404 page, so I think the guide's never been written :(

The tone knob on my Ms-2 is stuck, I can't move it. What do I have to do?
